.45-70 Government vs .450 Bushmaster

The .45-70 Government vs .450 Bushmaster debate centers on two big-bore hunting cartridges with different platform options. The .45-70 (325gr FTX at 2,000 fps) carries 2,050 ft-lbs at 100 yards, edging out the .450 Bushmaster's (250gr FTX at 2,200 fps) 1,868 ft-lbs. Penetration favors the heavier .45-70 at 28.4-28.9 inches versus 24.7-25.2 inches for the Bushmaster. Recoil differs noticeably: the .45-70 generates 36.29 ft-lbs compared to 25.15 ft-lbs for the .450 Bushmaster. The Bushmaster works in AR-platform rifles and meets straight-wall hunting regulations, while the .45-70 offers more energy from lever-action and single-shot platforms.
